9 Claims.

provide a box with scores and creases in the.

material whereby to close the top of a box with the formation of a spout when the material of the top is unfolded from its closed position.

Another object of the present invention is to provide a top closure for a box capable of forming a collapsible spout.

Still another object of the present invention is to provide in a single blank piece of material scores and creases adapting the material to be folded into a box having a collapsible spout closing an opening therein.

These objects and other objects made manifest in the descriptionto follow are obtained by the novel construction and improved arrangement of the parts embodying the invention and shown in the'accompanying drawing hereby made a part of this specification in which: v

Figure 1 is a fragmentary plan view of a' blank showing the sides and end sections for a box;

Figure 2 is a perspective view of a box embodying the invention when in an open position;

Figure 3 is aviewsimilarto Figure2 butwith the material in position for closing the opening in the box;

Figure 4 is an internal view of the box taken at the section indicated by the line 4-4 of Figure 3;

Figure 5 is a fragmentary plan view of a blank of material for forming a different form of the invention;

Figure 6 is a perspective view of a box and spout articulated from the blank shown in Figure 5;

Figure .7 is a section viewillustrating construction details and taken along the line 'l''! of Figure 6 when the spout is in the retracted position; and

Figure 8 is a view taken in cross-section at the line 8-3 of Figure 7.

Like reference characters indicate the same parts in the drawing and in the following description.

The fragment of a blank illustrated in Figure 1 shows an end structure for a box. Such blank includes a number of scores and extensions. The latter may be folded to form the end of a box in the same manner as the flaps of a con ventional box with a closed end.

Scores 19, ll, 12 and i3 divide the blank 14 into parts forming the sides 15, 16, i7 and 18 of the box. Blank it may be composed of a fibrous material like cardboard. Extending from side 15 is a narrow strip 19 to receive adhesive for securing the blank in an assembled position.

Separated from side 15 by a score 20 is an extension 21 the free edge of which is notched 00 at- 22. Side 16 has an extension 23 in which an incision 24 defines a tongue 25. A score 26 in alignment with score 20 separates extension 23 'andtthe side 16.

The side 17 has an extension 28 separated U5 therefrom by a score 27 in alignment with score 26. Extension 28 has a central section 284 in the form of a tongue and two side sections, the side sections being separated from the tongue 28:: by scores 29 in alignment with the contiguous edge ofthe tongue. Another score 30 divides each sidesection into sections 31and 32. Extension 33 projects from side 18 and is divided therefrom by score 34. A tongue 35 like tongue 25 but opposed thereto is separated from the body of the extension 33 by an incision 36.

The box is assembled by arrangin the four sides 15, 18, 1'1 and 18 as the four parallel sides of a parallelepiped. The narrow strip 19 is placed within the structure adjacent side 18 and is secured by any suitable adhesive material. The bottom part of the box (not shown) may be of standard construction and assembled in the usual manner.

The extensions 23 and 33.are folded 90 degrees inwardly of the box; The small section 19a at the top of the strip 19 is folded inwardly with the extension 33. Extensions 23 and 33 are of such a length that the tongues 25 and 35 are in close proximity when said extensions are folded inwardly. The extension 21 is folded to rest upon the top of the previously folded extensions with the edges of notch 22 coinciding with the space between the tongues 25 and 35 and the side 17 of the box.

The sectors 31 are brought inwardly and bent 180 degrees about the scores 29, to bring them contiguous to the main body of the extension 28. The sectors 32 are articulated 180 degrees in the opposite direction about the creases :30. When the extension 28 is folded on the score 27 to rest upon the top. of the box, the faces of the sectors 32-exposed in Figure l are within the notch 22 and lie upon the faces of the tongues 25 and 35. This is best shown in Figure 2. The E5 outer edges 3? of the sectors 32 are disposed in confronting relation to the edges 38 of notch 22. The faces of the sectors 32 are secured to the tongues 25 and 35 by suitable adhesive material. The exwnsion 28 serves as the bottomwali of a 1149 folding spout for the box while the sector sections 31 and 32 provide the sides of the spout.

Tongues and 35 are flexible and are extended outwardly of the box by extending section 28. Thus the tongues 25 and 35 only partially close the opening to the box and assist in the appor tionment of articles being emptied therefrom.

When it is desired to close the opening in the box, the extension 28 is bent over the top in the manner shown in Figure 3. In packaging a product within the box, the tip 28a may be secured to the extension 21 in a manner to hold the closure formed by the extension 28 in place until manually broken.

Figure 5 and the higher numbered figures illustrate a modified form of the invention. There is illustrated in Figure 5 a blank of material similar to that shown in Figure 1. Sides 41, 42, 43 and 44 are separated by the scores 45, 46 and 4'1. A section 48 at the edge of the side 44 is separated therefrom by a score 49.

The strip 48 has a short extension 50 which cooperates with the strip 48 to hold the box in assembly. Sections 41 and 42 have extensions 51 and 52. These sections are separated therefrom by scores 53 and 54, respectively.

Scores 55 obliquely disposed in the extension 52 separate tongues 56 from that extension. The outer edges of the tongues 56 are cut away to provide an inwardly extending opening 57 there= between.

From the side 43 projects an extension 58 with a score 59 therebetween. Creases 60 extend from the lower corners of the extension 58 inwardly to divide its middle section from two sectorlike sections 62 and 63 which are separated one from another by score lines 61. The central portion of the extension 58 has a tip 64 with an arcuate edge projecting therefrom, and is separated therefrom by score 64a.

From the side 44 and separated therefrom by a score 65a is an extension 65 having at its edge a notch 66 having edges 67, 68, and 69.

In assembling this type of box, the blank is foldedinto parallelepiped and adhesive disposed upon extension 48. Extension 51 is bent within the plane of the opening at the top of the box. Section 52 is folded over section 51 and is covered by extension 65 folded upon score 65a. The edges 67 and 68 are then parallel to the scores 55 of tongue 56. Sectors 63 are then attached to the tongues 56 by adhesive and are guided into position by placing the'edges 70' thereof against the edges 67 and 68 of the extension 65. At this time, the box will be assembled as shown in Figure 6, with the extension 58 and the tip 64 thereof projecting in the manner of a spout. Sectors 62 and 63, arranged somewhat in the manner of bellows, form sides for the spout.

The spout is closed over the opening 37 by bending it inwardly at the fold line 59 to displace the sections 62 and 63 about their intermediate creases 61 in the fashion of a bellows and to bring the extension 58 within the plane of the opening. Anterior to the closing of the opening the tip 64 of the extension may be bent normal thereto along the score 64a so that it may be inserted into the slit-like opening 55:: as shown in Figure 7.

What is claimed to be new and desired to be secured by Letters Patent of the United States is:
